1. TopBand: "Best" Receiver for 160 Work (score: 1): Author: w8ji.tom@MCIONE.com (w8ji.tom); Date: Sat, 02 Jan 1999 00:19:22 -0500; Hi Clive, Most rigs that work QSK click, especially on split frequency operation. Even if waveshape is good, the VCO's don't settle down totally before RF comes out. 73 Tom -- FAQ on WWW: http://www.; /archives//html/Topband/1999-01/msg00019.html (7,935 bytes)
